Pentax MX-1 vs Pentax Optio E90: A Hands-On Comparison for Photography Enthusiasts

When I first sat down to test the Pentax MX-1 alongside the Pentax Optio E90, I was struck by how two compact cameras from the same brand could serve such distinctly different user needs while occupying a similar category of small sensor compacts. Over years of testing and shooting thousands of images across environments - from city streets to rugged landscapes - I’ve come to appreciate how nuanced choices like sensor size, lens speed, and ergonomics shape the real-world usability of compact cameras.

In this detailed comparison, I’ll walk you through the strengths and limitations of each camera based on my hands-on experience, breaking down their performance across various photography disciplines, and technical capabilities. By the end, you’ll have a clear sense of which camera aligns best with your style and budget.

Size, Feel, and Controls: The Ergonomics That Shape Your Experience

The very first thing I noticed upon unboxing these two cameras is the difference in their physical presence in the hand.

Pentax MX-1 vs Pentax E90 size comparison

The Pentax MX-1 weighs 391 grams and measures approximately 122 x 61 x 51 mm, sporting a solid, retro-inspired metal body with a substantial grip. The heft and tactile finish inspired immediate confidence when shooting handheld, especially outdoors or during extended sessions. The controls, while classic, are easily accessible, making it conducive to manual exposure adjustments on the fly. This is ideal for photographers who enjoy having direct control over shutter priority, aperture priority, and manual exposure modes.

By contrast, the Pentax Optio E90 weighs just 145 grams and is considerably slimmer at 102 x 59 x 25 mm. It is unmistakably designed as a more casual, pocket-friendly point-and-shoot. Its lightweight body and smaller form factor make it highly portable for travel or casual street photography, but it sacrifices grip comfort and manual control ergonomics. The control layout is simplified, offering only fully automatic modes with limited exposure customization.

Moving on to the top panel comparison:

The MX-1 incorporates dedicated dials for ISO, exposure compensation, and aperture/shutter adjustments, which seasoned photographers will appreciate for quick changes without diving into menus. The E90’s controls are minimalistic, favoring a menu-driven interface suited for beginners or those prioritizing ease of use.

Sensor Technology and Image Quality: The Core Difference

At the heart of any camera’s imaging capability lies its sensor, and here the MX-1 clearly pulls ahead.

Pentax MX-1 vs Pentax E90 sensor size comparison

The Pentax MX-1 features a 1/1.7-inch CMOS sensor measuring 7.44 x 5.58 mm (41.52 mm²) with a resolution of 12 megapixels. This relatively large sensor for a compact camera allows for improved dynamic range and better low-light performance. Additionally, the sensor’s CMOS architecture enables faster readout speeds and advanced live view functions.

Conversely, the Optio E90 is equipped with a smaller 1/2.3-inch CCD sensor measuring just 6.08 x 4.56 mm (27.72 mm²) and 10 megapixels resolution. While CCD sensors historically deliver pleasing color rendition, they don’t perform as well in low light or high ISO due to higher noise levels and slower readout.

From practical shooting sessions, I found the MX-1 provides cleaner images up to ISO 800, with ISO 1600 still usable albeit with some noise. The Optio E90 tends to exhibit visible noise and color degradation beyond ISO 200 due to its sensor limitations.

In terms of dynamic range, the MX-1’s sensor can capture more nuanced highlight and shadow details, invaluable for landscape and portrait work where tonal gradation matters.

Rear LCD and User Interface

Viewing and composing images is another area where these cameras diverge significantly.

Pentax MX-1 vs Pentax E90 Screen and Viewfinder comparison

The MX-1 comes with a 3-inch tilting TFT LCD at 920k-dot resolution. This high-res screen renders images sharply and bright enough for daylight use. The tilt design enhances shooting flexibility, allowing comfortable framing at low or high angles - a feature I frequently used when photographing street scenes from waist height or low perspectives during macro captures.

On the other hand, the Optio E90 sports a fixed 2.7-inch LCD with only 230k dots resolution. The image quality on this display feels dated, with less clarity and responsiveness. I often found it challenging to judge sharpness and exposure on the E90’s screen outdoors on sunny days.

Both cameras lack touchscreens, which is understandable given their release timelines but worth considering if you prefer touch-focus or menu navigation.

Lens and Optical Performance for Varied Photography Disciplines

The lens remains a critical bridge between your subject and image sensor. Here’s where the MX-1’s bright, versatile optics stand out.

Pentax MX-1:

  • Fixed 28-112mm equivalent zoom (4x zoom)
  • Maximum aperture: F1.8 at wide, narrowing to F2.5 at tele
  • Sensor-shift image stabilization

Pentax Optio E90:

  • Fixed 32-95mm equivalent zoom (3x zoom)
  • Maximum aperture: F3.1 to F5.9 (noticeably slower lens)
  • No image stabilization

Portrait Photography

For portraits, the MX-1’s fast aperture and wider zoom range offer tangible benefits. The F1.8 aperture allows for subject isolation and creamy bokeh, especially when shooting headshots. I tested the MX-1 in natural light portrait scenarios and was impressed by the skin tone reproduction and smooth background blur. Furthermore, the MX-1’s 25 autofocus points combined with face detection yielded consistently sharp focus on eyes, critical for compelling portraits.

The Optio E90’s slower lens compromises depth of field control; portraits often looked flat with less separation from the background. Additionally, the limited AF system with just 3 points and no face detection made it harder to lock precise focus on moving subjects or off-center eyes.

Landscape Photography

The MX-1’s larger sensor and wider field of view at the wide end allowed me to capture landscapes with rich detail and vibrant color fidelity. The improved dynamic range mitigated highlight clipping, preserving sky gradients even under bright sun.

Being weather-sealed (although not explicitly stated in specs, it is important to mention - both cameras lack environmental sealing) is critical for rough outdoor use - unfortunately, neither model offers this. But the MX-1’s build feels more robust for travel and landscape shooting.

The Optio E90’s smaller sensor and narrower lens limit landscape compositions, and the higher noise floor hinders image quality in shadows or low-light dusk scenarios.

Wildlife and Sports Photography

Thanks to its contrast-detection AF system with face tracking and continuous AF mode, the MX-1 can handle casual wildlife or sports photography better. However, its 1 fps burst shooting speed is quite slow, limiting action capture potential.

The E90 lacks any continuous AF or burst mode, making it unsuited for fast subjects.

Street and Travel Photography

Here, size and discretion play a bigger role. The E90, with its small footprint and light weight, is an ideal pocket companion for spontaneous street photography. Its quiet shutter and lightweight body helped me remain unobtrusive in urban environments.

The MX-1, while larger, still fits into a jacket pocket and offers faster control response and image quality advantages - though it’s more conspicuous.

Macro and Night Photography

The MX-1 shines as a macro tool with its focusing distance down to 1 cm and sensor-shift image stabilization. I enjoyed capturing fine detail of flowers and insects handheld. The stabilization made a real difference at close distances by mitigating hand shake blur.

The E90’s closest focusing range is 6 cm, which restricts fine macro work. Additionally, it lacks stabilization, necessitating a tripod at close distances or slower shutter speeds.

For night and astrophotography, the MX-1’s higher max ISO (up to 12800) and longer shutter speed abilities (up to 30 seconds) opened creative possibilities. While noise becomes a factor, noise reduction and black-level offset controls provide decent results. The E90’s ISO tops at 3200 but is only about usable at ISO 80–200, making it far less capable after sunset.

Video Capabilities

Video is increasingly vital, so I tested the recording features thoroughly.

The MX-1 records Full HD 1080p video at 30 fps with H.264 compression. It also supports 720p at 60 fps for smooth slow-motion capture. Unfortunately, no microphone input means audio quality depends on the built-in mic, which tends to pick up handling noise.

The Optio E90 records at 720p but limited to 15 fps - a noticeably choppy video experience - using Motion JPEG format. There’s no HDMI output and no mic port, so it’s more of a casual video snapshot tool than semi-pro video device.

Build Quality, Battery Life, and Connectivity

The MX-1’s metal body and solid construction felt reassuring during field tests. Despite lacking weather sealing, the heft contributes to durability.

The E90 is plasticky and light, aimed more for casual vacation use rather than serious rugged shooting.

Battery life on the MX-1 is rated at 290 shots per charge using the proprietary D-Li-106 battery. In real life, expect about 250 reliable shots per charge when using live view and flash sparingly. The E90 runs on two AA batteries, which some may find convenient for easy replacement abroad - ideal for travelers - but these provide less predictable power longevity.

Connectivity-wise, the MX-1 supports Eye-Fi cards for wireless image transfer and has HDMI output. The E90 offers none of these modern conveniences, reflecting its budget-targeted design.

Price and Value: What You Get for Your Money

The Pentax MX-1 originally priced around $400 offers significant bang for the buck, punching well above typical point-and-shoots with a combination of solid image quality, fast lens, manual controls, and video capabilities. Several years on, you can find it used for approximately $200–$250, representing excellent value for enthusiasts wanting a compact yet capable all-around shooter.

The Optio E90, priced at under $100 new or used, targets budget-minded casual users who want an ultra-simple compact for snapshots. Its compromises in sensor, lens speed, and controls limit growth potential beyond basic photography.

Real-World Image Gallery

Let me share some sample images captured with both cameras under various conditions to illustrate these points:

The MX-1 samples (first row) exhibit richer colors, smoother gradation, and better detail retention. The E90 images (second row) look softer with less dynamic range and more noise in shadows.

Overall Performance and Scoring

Based on rigorous side-by-side testing using standardized protocols covering image quality, autofocus, handling, and features, here is how they measure up overall:

The MX-1 earns a respectable score reflecting its advanced sensor and lens combo, good ergonomics, and flexible shooting modes. The E90 ranks modestly, adequate for casual use but significantly outperformed in most technical criteria.
